I have just installed an ATHLON ll -240 REGOR-65W w/ 2G DDR2 8500 (KHX85002K/2 KINGSTON HYPERX) on a Gigabyte GA-MA78LM-S2H board which lists this processor and memory as compatible. I can not get the system to recognize the 1066 - it immediately resets to 800. Even if use only I stick - 1066 will not hold and in fact will not load wanting to cycle through start up.

The following from GigaByte:
Dear Customer
1066 memory should be ok to be used, whether if it can operate at those spec we are unable to determine. Do note that the memory controller is integrated onto the processor

If you could expand on that a little I'd appreciate it ... who is they and then I guess, why not .. please understand I am not being contentious, as a hobby builder I depend on the board manual to make my decisions as well as any hardware site ... so if the manual says I can use 1066 I assume that's what they mean. Ironically the blurb on the board says increase your esperience w/1200 DD2
And as I think about it - it is not kicking into DDR2 - either - its unganged ...
Thanks for reply

***** I hate being the dumb guy in class ... I understand what you are saying and then again I don't.
The OC utility w/ this board allowed me to up the FSB to around 260 which gave me a memory speed of 1044 +/-. Board responed for about 5 minutes when it reset closing W-Xp.
So I guess my question is: which is the culprit - the board or the cpu or the memory.

I have about 10 machines to upgrade and I can't be going through this with every one. We were looking at this board for it's "flexibility". This ain't it. Suppose we went to a Phenom II ....
